Configure Qt5 on QNX 6.5.0 sp1

madalff

I was using 5.0 version, downloaded from http://qt-project.org/downloads
I'm just wondering is there any person who managed to build qt5 on QNX

Maybe I use wrong options for configure script

I was able to build Qt5 for QNX. I was using the playbook sdk but I don't think it is too different from BB10 if that is what you have.

I use a shell script to configure the environment

@
ron@linux-tsia:~> cat configure-qt5-blackberry.sh
#!/bin/bash

script to configure shell for QT5-blackberry

QTDIR=$HOME/development/qnx/qt-5.0.1/usr/qt5
PATH=$QTDIR/bin:$PATH
MANPATH=$QTDIR/doc/man:$MANPATH
LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

. $HOME/bbndk-2.1.0/bbndk-env.sh

export QTDIR PATH MANPATH LD_LIBRARY_PATH QNX_TARGET QNX_HOST QNX_CONFIGURATION MAKEFLAGS

/bin/bash
@

The environment file 'bbndk-env.sh' from the blackberry development kit:

@
ron@linux-tsia:~> cat $HOME/bbndk-2.1.0/bbndk-env.sh

This script is sets environment variables requires to use this version of NDK

from the command line. To use the script, you have to "source" it into your shell,

source bbndk-env.sh

if source command is not available use "." (dot) command instead

QNX_TARGET="$HOME/bbndk-2.1.0/target/qnx6"
QNX_HOST="$HOME/bbndk-2.1.0/host/linux/x86"
QNX_CONFIGURATION="$HOME/.rim/bbndk"
MAKEFLAGS="-I$QNX_TARGET/usr/include"
LD_LIBRARY_PATH="$QNX_HOST/usr/lib:$LD_LIBRARY_PATH"
PATH="$QNX_HOST/usr/bin:$QNX_CONFIGURATION/bin:$QNX_HOST/usr/qde/eclipse/jre/bin:$PATH"

export QNX_TARGET QNX_HOST QNX_CONFIGURATION MAKEFLAGS LD_LIBRARY_PATH PATH
@

And the configuration that I used to compile Qt5:

@
configure -xplatform blackberry-armv7le-qcc -opengl es2 -nomake docs -nomake examples -nomake demos -nomake tests -opensource -confirm-license -release -no-neon -no-c++11 -prefix $HOME/development/qnx/qt-5.0.1/usr/qt5
@

Qt5 location: $HOME/development/qnx/qt-5.0.1/usr/qt5
The bbndk is in the default directory: $HOME/bbndk-2.1.0/
Qt5 installation target: $HOME/development/qnx/qt-5.0.1/usr/qt5

I deleted the folders qtdoc, qttools, qtwebkit, and qtwebkit-examples-and-demos from the source tree as they probably won't compile for this platform and are not needed. The nomake options should ignore these directories anyway.

So you could actually have Qt 5 applications running on the BlackBerry Playbook.
I found some more info about it on the internet which might be helpful to this topic:

https://github.com/preet/scratch/wiki/Qt-5.1-on-the-Playbook
*http://www.kdab.com/qt5-on-the-qnx-operating-system/

Is anybody crazy enough to create some apps for the dead little tablet?

Cheers.

Rondog

Yeah, I get the impression it is dead. It is too bad because I have gotten kind of fond of it especially after trying to use the smaller touch screen on my Samsung phone.

I haven't tried the new version of Qt with this slab. I found that 4.8.x and 5.0.x had some issues that required a work around or two but you could end up with a usable application.

I am still waiting for OS upgrade to BB10 update for the Playbook; this should be more compatible with Qt.

Hey, haven't you heard the news? BB10 is definitely "not coming to the Playbook.":http://www.trustedreviews.com/news/blackberry-playbook-bb10-update-cancelled-confirms-heins
Yeah, too bad. But Qt apps run really fine on it anyway so I guess one could make a few thousand bucks with not much effort. I guess the main annoyance is that there's no Qt on the system so the apps are somewhat big thus, the code-deploy-test-fix cycle would be very slow.

tzander

To have a lower test-fix deploy cycle I copied the Qt libs on there and pointed my apps LD_LIBRARY_PATH to that dir, this way my debug builds only upload the actual app.

Works on BB10 too.

./configure -xplatform qnx-x86-qcc -static -debug
gives me the following error: The specified system/compiler is not supported:

How to configure properly?
Any help is much appreciated.[/quote]

Hi!
Change in
qt-everywhere-opensource-src-5.1.1/qtbase/configure
line 268:
[code]
PLATFORM=unsupported/qnx-g++
[/code]
to
[code]
PLATFORM=qnx-x86-qcc
[/code]
configure will work.
But I can`t build Qt, because it break with some link errors:

/bin/sh: QNX_TARGET: cannot execute - No such file or directory
in
qcc -Vgcc_ntox86 -o "/qt-src-5.1.1/qtbase/bin/qmake" project.o .... many-many files *.o -Wl,-rpath-link,$(QNX_TARGET)/x86/usr/lib

Rondog

It sounds like you don't have the variable QNX_TARGET set properly. On my system it is set like this:

QNX_TARGET="/Users/ron/bbndk-2.1.0/target/qnx6"

You can see what the current value of this variable is set to using the 'echo' command from the console

@
bash-3.2$ echo $QNX_TARGET
/Users/ron/bbndk-2.1.0/target/qnx6
bash-3.2$
@

If you do have it set then maybe the location is wrong?

Thank you for answer.
QNX_TARGET variable in my QNX system sets to

/usr/qnx650/target/qnx6

I suggest, that error in file
/qt-everywhere-opensource-src-5.1.1/qtbase/mkspecs/common/qcc-base-qnx.conf

@...
QNX_DIR = $$(QNX_TARGET)
isEmpty(QNX_DIR) {
error("QNX_TARGET environment variable not set")
}

QMAKE_INCDIR = $${QNX_DIR}/usr/include $${QNX_DIR}/usr/include/freetype2
QMAKE_LIBDIR = $${QNX_DIR}/$${QNX_CPUDIR}/lib $${QNX_DIR}/$${QNX_CPUDIR}/usr/lib
QMAKE_LFLAGS += -Wl,-rpath-link,$${QNX_DIR}/$${QNX_CPUDIR}/lib -Wl,-rpath-link,$${QNX_DIR}/$${QNX_CPUDIR}/usr/lib
...@

Result of this script

qcc -Vgcc_ntox86 -o "/qt-src-5.1.1/qtbase/bin/qmake" project.o ... -lang-c++ -Wl,-rpath-link,$(QNX_TARGET)/x86/lib -Wl,-rpath-link,$(QNX_TARGET)/x86/usr/lib

looks like a wrong. I suppose, that instead QNX_TARGET variable must be value of QNX_TARGET.
Also unknown -rpath-link parameter present. May be typo error?

All my attempts to correct script were unsuccessful
